A Boston police officer at the center of an Attorney General's investigation allegedly played slots at a Plainville casino using cash from the department's Hyde Park evidence room.

A Suffolk County grand jury indicted Joseph Nee, 44, on a charges of larceny over $250 and money laundering on Thursday. Nee has been suspended without pay from his evidence management position in the department's Central Supply Unit following the investigation, according to a statement from AG Maura Healey's office.

Nee has been a member of BPD since 1998.

The money derived from a bank robbery and reportedly still bore traces of red dye after an anti-theft ink pack discharged during the commission of the crime, the statement said.

The lawman allegedly took roughly $2,000 total, using some of the stolen bills at a slot machine at Plainridge Park Casino on Washington Street in Plainville, and he also tried to exchange some of the red-tainted bills for fresh ones at a casino kiosk, according to the AG.

A Suffolk Superior Court arraignment date has been scheduled for Oct. 30, according to the statement.
